Description

机器类通讯终端信息的获取方法和系统 技术领域 本发明涉及通信领 i或, 具体而言, 涉及一种机器类通讯 ( Machine Type Communication, 简称为 MTC ) 终端信息的获取方法和系统。 背景技术 在传统的移动网络月艮务中, 人对人 ( Human To Human , 简称为 Η2Η ) 通讯占据了主要的位置。在 Η2Η通讯中, 由于参与的双方为具有行为控制能 力的人, 因此会话实际上由人的行为控制。 随着移动网络服务和自动化控制 技术的发展, 目前, 出现了一种新的移动通讯方式, 即机器对机器( Machine To Machine, M2M ) 的通讯, 在该通讯方式中, 通讯的双方为机器设备。 狭义的 M2M定义是机器到机器的通信, 但从广义上说 M2M 包括以机 器终端智能交互为核心的、 网络化的应用与月艮务。 M2M基于智能机器终端、 以多种通信方式为接入手段, 可以为客户提供的信息化解决方案, 用于满足 客户对监控、 指挥调度、 数据釆集和测量等方面的信息化需求。 M2M 可以 应用于行业应用 (例如, 交通监控、 告警系统、 海上救援、 自动售货机、 开 车付费等)、 家庭应用 (例如, 自动抄表、 温度控制等) 及个人应用 (例如, 生命检测、 远端诊断等) 等。 与人对人通讯的最根本的不同在于, M2M 的通信对象为机器, 通讯行 为是自动化控制的, 即通讯的发起、 通讯的终止、 通讯过程中的一些准入和 限制的控制, 均是自动化的行为。 这种行为, 依赖于 M2M通讯中对机器(即 M2M通讯中的终端)行为的约束和控制, M2M通讯中的终端的行为受业务 签约数据约束, 网络才艮据业务签约数据对 M2M通讯中的终端进行管理。
M2M通讯, 也称为机器类通讯 ( Machine Type Communication, 简称为 MTC ), 最典型的为终端和应用月艮务器之间的通讯, 该终端被称为 MTC终端 ( MTC User Equipment , 简称为 MTC UE ), 应用月艮务器被称为 MTC月艮务器 ( MTC Server )„ 在 2G/3G/LTE接入下, M2M通讯主要以分组 (Packet Service, 简称为 PS )网络作为底层承载网络, 实现 MTC终端和 MTC服务器之间的业务层通 讯。 图 1是 M2M通讯实体接入到演进的分组系统 ( Evolved Packet System, 简称为 EPS ) 的架构示意图。 在图 1中, 底层承载网络包括: 演进的通用移动通信系统陆地无线接入 网 ( Evolved Universal Terrestrial Radio Access Network, 简称为 E-UTRAN )、 移动管理单元( Mobility Management Entity,简称为 MME ),月艮务网关( Serving Gateway, 简称为 S-GW, 或 SGW ),分组数据网络网关( Packet Data Network Gateway, 简称为 PDN GW, 或 P-GW, 或 PGW)、 归属用户月艮务器 (Home Subscriber Server , 简称为 HSS )、 策略和计费规则功能实体 (Policy and Charging Rules Function, 简称为 PCRF )。 其中, E-UTRAN 的主要网元是 eNodeB ( Evolved NodeB , 基站)。 在图 1 中, MME 负责移动性管理、 非接入层信令的处理、 以及用户移 动管理中上下文的管理等控制面的相关工作; S-GW是与 E-UTRAN相连的 接入网关设备, 在 E-UTRAN和 P-GW之间转发数据, 并且负责对寻呼等待 数据进行緩存; P-GW则是 EPS与分组数据网络 (Packet Data Network, 简 称为 PDN ) 的边界网关, 负责 PDN的接入及在 EPS与 PDN间转发数据等 功能; PCRF是策略和计费规则功能实体, 它通过接收接口 Rx和运营商网络 协议 (Internet Protocol, 简称为 IP ) 业务网络相连, 获取业务信息, 此夕卜, 它还可以通过 Gx接口与网络中的网关设备相连, 负责发起 IP承载的建立, 保证业务数据的服务质量 (Quality of Service, 简称为 QoS ), 并进行计费控 制。 HSS提供用户的签约数据的管理, 和用户接入到网络中的重要的上下文 信息的管理。 在图 1中, MTC UE通过 E-UTRAN ( eNodeB )接入到 EPS网络中, 在 被分配 IP地址后, MTC UE与 MTC Server之间可以建立起 IP通道, 从而实 现与 MTC Server之间的上层业务通讯。 MTC UE与 MTC Server之间所建立 的 IP通道为一条還辑上的 IP通道,其物理路径经过: eNodeB、 S-GW、 P-GW。 目前, 实现 M2M通讯的一种方式是在 MTC UE与 MTC Server之间的 IP 通道上建立一个业务层接口协议, 通过该业务层接口协议, MTC UE 和 MTC Server交互业务数据, 同时, MTC Server也通过该业务层协议实现对 MTC UE的控制。 图 2描述该种方式实现 M2M通讯的流程,如图 2所示,在该方式中 MTC
UE通过 PS网络接入, 实现和 MTC Server建立通讯连接主要包括以下步骤: 5201 , MTC UE向 MME发起附着请求;
5202, MME接收上述附着请求, 向 HSS发送位置更新请求, 在该步骤 中, HSS向 MME下载 MTC UE的签约数据, 其中包含用于 M2M接入控制 的签约数据部分; S203 , MME向 SGW/PGW发送 载创建请求,请求 SGW/PGW为 MTC
UE创建合适的^载;
5204 ,如果 PGW需要从 PCC获得策略数据以据此建立合适的承载 , PGW 和 PCC交互以获得 PCC策略;
5205 , PGW为 MTC UE创建 载, 返回 载创建响应; S206, MME向 MTC UE发送附着响应; 步骤 S026后, MTC UE已经附着到 PS网络, 被分配了 IP地址, 并建 立和合适的 载, 从而可以向 MTC Server发起业务层的注册。
5207, MTC UE向 MTC Server发起业务层的注册;
5208, MTC Server接受 MTC UE的注册, 返回注册响应; S209, 后续 MTC UE和 MTC Server之间通过业务层协议交互数据。 通过图 2所示的流程, MTC UE接入到 PS网络, 建立了和 MTC Server 之间的 IP连接, 从而可以实现后续和 MTC Server之间的业务层通讯。 在该 流程中, 由于 MTC Server和底层接入层 (指 MME/SGW/PGW等网元)之间 没有任何联系, 因此, MTC Server无法获得底层接入层发生的事件, 从而无 法根据这些事件来判断 MTC UE的行为是否正常,对于某些需要业务层具备 较高控制权的 M2M业务(如高可用性 M2M通讯、具有智能管理能力的 M2M 通讯等), 釆用上述接入方式将无法实现。 例如, 在某些高可用性 M2M通讯中, MTC月艮务器出于智能管理和实时 监控 MTC终端设备的目的,需要经常性地检查 MTC终端设备接入网络的情 况, 以确认 MTC终端设备运作正常。 另一方面, 如果 MTC终端设备接入网 络的行为异常, 则 MTC服务器需要及时了解异常情况, 以及时通知 M2M运 营维护人员进行现场维护。 或者, 在设备可能存在偷盗的情况下, MTC服务 器需要有能力及时探测可能的设备被偷盗和系统被盗用的情况, 以便及时地 作出反应。 尤其在智能管理和实时监控要求比较高的 M2M通讯中,对 MTC服务器 而言, 为了满足较高的管理要求, MTC服务器可能需要及时地获知 MTC终 端设备接入网络的情况, 典型地, MTC服务器可能需要获取与 MTC终端的 以下信息:
( A )定时接入监控: 对某些业务, 需要限制 MTC终端设备的接入到网 络的时间, 如果发生非允许时间接入网络, 则 MTC服务器需要及时获得该 情况; ( B ) 区域接入限制: 对某些业务, 需要限制 MTC终端设备从什么位置 区域接入到网络, 如果发生从不允许的位置区域接入到网络, 则 MTC服务 器需要及时获得该情况;
( C )移动性限制: 对某些业务, 只允许 MTC中断设备在预先设定的区 域定移动, 或者不允许 MTC终端设备频繁地发生移动, 如果上述这些不允 许的移动性行为发生, 则 MTC服务器需要及时获得该情况;
( D ) SIM盗用检查: 由于 M2M通讯的资费可能比通常的移动通讯资 费要低, 如果 MTC终端设备的 SIM卡被盗用, 将会对业务运营商带来损失。 为了防范这类情况的发生,业务运营商可能要求 SIM卡中的国际用户识别码 ( International Mobile Subscriber Identification Number,简称为 IMSI )和 MTC 终端设备的国际移动设备识别码( International Mobile Equipment Identity, 简 称为 IMEI )进行绑定, 即一个 IMSI只能由某一个具有特定 IMEI的 MTC终 端设备使用。 在这种情况下, MTC服务器需要对 MTC终端的 IMSI和 IMEI 绑定进行-险证。 对上述这些业务需求, MTC 终端的相关信息均只有底层的接入层 载 层能够获得, 在 E-UTRAN接入下只有 ΜΜΕ能够获得必要的信息并加以判 断。 从现有 Μ2Μ通讯 (此处指 MTC UE和 MTC Server之间的通讯 )接入 到 EPS 的架构看, MTC 艮务器无法获知上述这些信息, 从而影响了智能管 理、 实时监控类业务的实现。 发明内容 针对现有技术中由于 MTC服务器无法获取 MTC终端的接入层 /承载层 等信息而导致无法对 MTC终端进行有效控制的问题而提出本发明, 为此, 本发明的主要目的在于提供一种改进的 MTC终端的控制方案, 以解决上述 问题至少之一。 为了实现上述目的, 才艮据本发明的一个方面, 提供了一种 MTC终端信 息的获取方法, 该方法应用于包括移动性管理网元和 MTC月艮务器的系统, 其中, 移动性管理网元与 MTC服务器相连。 才艮据本发明的 MTC终端信息的获取方法包括: MTC 艮务器通过移动性 管理网元获取当前请求附着到网络或当前已附着到网络的 MTC终端的信息。 为了实现上述目的, 根据本发明的另一方面, 提供了一种 MTC终端信 息的获取系统。 才艮据本发明的 MTC终端信息的获取系统包括: 用户签约数据存储器、 移动性管理网元和 MTC服务器。 其中, 用户签约数据存储器, 用于保存系 统内的 MTC终端的签约数据; 移动性管理网元, 与用户签约数据存储器连 接, 用于接收用户签约数据存储器下发的请求附着到网络的或已附着到网络 的 MTC终端的签约数据, 并向 MTC月艮务器提供 MTC终端的信息; MTC 服务器, 与移动性管理网元连接, 用于从移动性管理网元获取 MTC终端的 信息。 进一步地, 上述 MTC月艮务器还与用户签约数据存储器连接, 用于从用 户签约数据存储器获取为 MTC终端分配的移动性管理网元的地址。 通过本发明, MTC服务器与移动性管理网元连接, 从移动性管理网元获 取 MTC终端设备的有关接入层 /承载层的信息,解决了现有技术中由于 MTC 服务器无法获取 MTC 终端设备的接入层 /承载层的信息而导致无法对 MTC 终端设备进行有效控制的问题, 进而达到使得 MTC服务器可以有效判断和 控制 MTC终端设备的行为。 附图说明 此处所说明的附图用来提供对本发明的进一步理解, 构成本申请的一部 分, 本发明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的 不当限定。 在附图中: 图 1是相关技术中 M2M通讯实体接入到 EPS的架构示意图; 图 2是相关技术中 MTC UE通过 PS网络接入并与 MTC月艮务器建立通 讯连接的流程图; 图 3是才艮据本发明实施例的 MTC UE信息的获取系统结构示意图; 图 4是才艮据本发明实施例的 MTC UE通过 EPS系统接入实现 M2M通讯 的架构图; 图 5是才艮据本发明实施例的 MTC UE通过 GPRS系统接入实现 M2M通 讯的架构图; 图 6为才艮据本发明实施例的 MTC终端信息的获取方法的流程图; 图 7为本发明实施例中一种 MME主动向 MTC Server上 4艮 MTC UE的 信息的流程图; 图 8为本实施例中另一种 MME主动向 MTC Server上 4艮 MTC UE的信 息的流程图; 图 9为本实施例中 MTC Server通过 MTC UE的 GUTI获取为该 MTC UE 分配的 MME的地址的 ¾ϊ程图; 图 10为本实施例中 MME主动通知 MTC Server该 MME的地址的流程 图; 图 11为本实施例中 MTC Server通过 HSS获取为 MTC UE分配的 MME 的地址的流程图; 图 12为本实施例中 MTC Server通过向 MME发送查询请求获取 MTC UE的信息的流程图; 图 13为本实施例中 MTC Server向 MME订阅 MTC UE的相关事件获取 该 MTC UE的信息的流程图。 具体实施方式 现有技术中, 无论 MTC UE通过 EPS网络接入实现 M2M通讯, 还是通 过 GPRS网络接入实现 M2M通讯, MTC月艮务器均无法获知 MTC UE的接 入层 /承载层的相关信息, 从而无法实现对 MTC UE的智能管理或实时监控, 针对该问题, 本发明实施例提供了一种 MTC UE信息的获取方案。 在本发明 实施例中, MTC月艮务器与移动性管理网元 (在 MTC UE接入到 E-UTRAN 网络时为 MME,在 MTC UE接入到 GSM/EDGE无线接入网络( GSM/EDGE Radio Access Network, 简称为 GERAN ) /UTRAN网络时为月艮务通用分组无 线业务支撑节点 ( Serving General packet radio service support node, 简称为 SGSN ) )相连, MTC服务器通过移动性管理网元获取 MTC UE的接入层 /承 载层等相关信息, 并根据获取的信息对该 MTC UE进行控制。 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互组合。 才艮据本发明的实施例, 提供了一种 MTC终端的控制系统。 图 3为才艮据本发明实施例的 MTC终端的控制系统的结构示意图,如图 3 所示, 根据本发明实施例的 MTC终端的控制系统主要包括: 用户签约数据 存储器 1、 移动性管理网元 3和 MTC服务器 5。 下面分别对上述各个网元进 行描述。 其中,用户签约数据存储器 1 ,用于保存系统内的 MTC终端的签约数据; 移动性管理网元 3 , 与用户签约数据存储器 1连接, 用于接收用户签约 数据存储器 1下发的请求附着到网络的或已附着到网络的 MTC终端的签约 数据, 并向 MTC服务器 5提供该 MTC终端的信息; 例如, 在 MTC UE请求附着到网络时, MTC UE将向移动性管理网元 3 发送附着请求, 移动性管理网元 3在接收到 MTC UE的附着请求后, 向用户 签约数据存储器 1发送位置更新请求, 用户签约数据存储器 1在接收到位置 更新请求后, 向移动性管理网元 3下发该 MTC UE的签约数据, 移动性管理 网元 3接收并存储该签约数据。 在 MTC UE附着到网络后, 如果该 MTC UE 的签约数据发生变化, 则用户签约数据存储器 1将向移动性管理网元 3下发 更新后的该 MTC UE的签约数据。
MTC服务器 5 , 与移动性管理网元 3连接, 用于从移动性管理网元 3获 取的上述 MTC终端的信息。 在本发明实施例中, 在现有架构上, 增加 MTC服务器 5和移动性管理 网元 3之间的接口, 以使 MTC服务器 5和移动性管理网元 3之间可以进行 通信。 进一步地, 如图 3所示, MTC服务器 5还可以直接与用户签约数据存储 器 1连接, 即 MTC服务器 5与用户签约数据存储器 1之间存在相互连接的 接口,从而使得 MTC服务器 5可以从用户签约数据存储器 1获取为 MTC UE 分配的移动性管理网元 3的地址。 在具体应用中, 在 MTC UE附着到网络后, MTC UE通过网络向 MTC 服务器 5发起注册, MTC服务器 5在接收到注册请求后, 可以通过与用户签 约数据存储器 1之间的接口,获取为该 MTC UE分配的移动性管理网元 3的 地址, 然后可以通过获取的移动性管理网元 3的地址, 从与该地址对应的移 动性管理网元 3中获取该 MTC UE的信息。 例如, 在 MTC UE接入到 E-UTRAN网络时, 上述用户签约数据存储器 1为 HSS , 移动性管理网元 3为 MME; 在 MTC UE接入到 GERAN/UTRAN 网络时, 用户签约数据存储器 1为 HLR, 移动性管理网元 3为 SGSN。 下面通过具体实施例对本发明实施例提供的上述系统进行说明。 实施例一 本实施例以 MTC UE 利用 EPS 系统实现接入 (即 MTC UE 接入到 E-UTRAN网络) 为例进行说明。 图 4为本实施例中 MTC UE通过 EPS系统接入实现 M2M通讯的架构图, 如图 4所示, 在本实施例中, MTC月艮务器与 MME之间实现了连接, 以便 MTC服务器从 MME获得 MTC UE的底层接入层 /承载的信息,以判断 MTC UE的行为。 如图 4所示, 在本实施例中, MTC Server和 MME建立了接口, 为了方 便描述,在本实施例中将该接口称之为 M2M-MME。通过该接口, MTC Server 可以向 MME查询或订阅和某个 MTC UE相关的底层接入层的事件, 如: MTC UE附着到 PS网络、 MTC UE从 PS网络去附着、 MTC UE在 PS网络 中发生了位置移动等。 或者, 通过该接口, MME可以将和某个 MTC UE相 关的底层接入层的事件, 主动通知给 MTC Server。 从而, MTC Server可以 获得 MTC UE的底层接入层信息, 并根据这些接入层信息判断 MTC UE的 行为, 从而执行合适的控制。 可选地, 在该架构中, 可以在 MTC Server与 HSS之间建立接口, 为了 方便描述,本实施例中将该接口称之为 M2M-HSS。通过该接口, MTC Server 可以从 HSS查询到 MTC UE的签约数据, 根据这些签约数据, MTC Server 可以判断 MTC UE是否有违反业务签约的行为出现,进而可以执行进一步的 控制。 或者, 通过该接口, MTC Server可以从 HSS查询到为 MTC UE分配 的 MME的地址。 在具体应用中, 如果 MTC Server和 HSS之间不建立 M2M-HSS接口, MTC Server可以通过与 MME之间的 M2M-MME接口, 获得 MME中保存 的 MTC UE的签约数据。 并且, MTC Server可以主动向 MME查询 MTC UE 的签约数据;或者,也可以由 MME主动将 MTC UE的签约数据发送给 MTC Server„ 实施例二 本实施例以 MTC UE接入到 GERAN/UTRAN网络为例进行说明。 图 5为本实施例中 MTC UE通过 GERAN/UTRAN网络接入实现 M2M 通讯的架构图, 如图 5所示, 本实施例基本与上述系统实施例一相似, 不同 之处在于, GERAN/UTRAN网络中的 SGSN相当于 E-UTRAN网络中 MME, 用于实现 PS域的接入控制和移动性管理功能,而 GERAN/UTRAN网络中的 网关 GPRS支持节点 ( Gateway GPRS Support Node, 简称为 GGSN )相当于 E-UTRAN 网络中的 SGW 和 PGW, GERAN/UTRAN 中的 HLR 相当于 E-UTRAN 网络中的 HSS。 其具体连接及各个网元的功能与上述系统实施例 一相似, 在;^不再赘述。 才艮据本发明实施例, 还提供了一种 MTC UE信息的获取方法, 该方法可 以通过根据本发明实施例提供的上述系统实现。 才艮据本发明实施例的 MTC UE信息的获取方法包括: MTC服务器通过 与移动性管理网元之间的接口,获取请求附着到网络或已附着到网络的 MTC 终端的信息。 具体地, 如图 6所示, MTC Server获取当前请求附着到网络或已附着到 网络的 MTC UE的信息主要包括以下步骤 (步骤 S601 -步骤 S603 ): 步骤 S601 : 移动性管理网元向 MTC服务器上 4艮 MTC终端的信息; 步骤 S603: MTC服务器获取移动性管理网元上报的 MTC终端的信息。 在具体实施过程中,移动性管理网元向 MTC月艮务器上 4艮 MTC终端的信 息包括但不限于以下三种方法: (一) 移动性管理网元主动向 MTC Server上报 例如, 移动性管理网元可以在某个 MTC UE的接入层 载层事件发生 时, 主动通知 MTC Server, 或者, 移动性管理网元主动向 MTC Server上 4艮 某个 MTC UE的信息。

MTC Server在获取到为 MTC UE分配的移动性管理网元的地址后, MTC Server可以在需要的时候, 向该移动性管理网元发送上述查询请求, 具体地, MTC Server 确定需要向移动性管理网元发送查询请求的情况包括但不限于 以下之一:
( A ) MTC Server需要获知 MTC UE所使用的 IMSI、 IMEI, 以检测为 MTC UE配备的 SIM卡是否被盗用, 即判断 IMSI、 IMEI绑定关系是否正常;
( B ) MTC Server需要获知 MTC UE的当前的位置信息 (例如, TA区 域、 Cell小区等), 以判断 MTC UE是否在不被允许的位置区域接入; ( C )MTC Server需要获知 MTC UE的当前的位置信息,以判断 MTC UE 是否移动到不被允许的位置区域;
( D ) MTC Server需要判断 MTC UE是否在不被允许的时间接入;
( E ) MTC Server需要判断 MTC UE接入到网络的时间是否超过预定时 长。 以 E-UTARN网络为例, 图 12为 MTC Server向 MME发送查询请求, 以获取 MTC UE的接入层 /承载层的信息的流程图,如图 12所示, MTC Server 向 MME发送查询请求, 获取 MTC UE的信息主要包括以下步 4聚:
5211 , MTC UE附着到 PS网络;
5212, MTC UE向 MTC Server发起业务层注册; S213 , 当 MTC UE注册到 MTC Server后, 如果 MTC Server出于业务控 制的目的, MTC UE决定需要查询 MTC UE的当前信息(主要指接入层信息); 在该步骤中, MTC Server可能出于多种可能目的需要获得 MTC UE的 信息, 例 ¾口:
MTC Server希望得知 MTC UE所使用的 IMSI、 IMEI情况, 以检 -险为 MTC UE所配备的 SIM卡是否被盗用, 即 IMSI、 IMEI绑定关系是否正常; 或者, MTC Server希望得知 MTC UE的当前的位置信息(如 TA区域、 Cell小 区等), 以判断 MTC UE是否在不被允许的位置区域接入, 或者是否移动到 不被允许的位置区域。
S214, MTC Server向 MME发送查询请求以查询 MTC UE的信息; S215 , MME才艮据 MTC UE的当前上下文, 返回 MTC UE的当前信息。 通过步骤 S213 - S215 , MTC Server从 MME处获得了 MTC UE的当前 信息, 从而可以才艮据 MTC UE的当前信息, 判断 MTC UE的当前行为, 进 一步可对 MTC UE的行为做出控制。 具体地, 在上述步骤 S213中, MTC Server向 MME请求的 MTC UE的 信息包括但不限于以下之一或其任意组合:
A) MME从 HSS处获得的 MTC UE当前业务签约数据。
B) MTC UE所使用的 IMSI、 IMEI; 具体地, MTC UE所使用的 IMSI 是 MTC UE在附着到网络时在附着消息中必须携带的, MME可以从附着消 息中获取 MTC UE使用的 IMSI , 而 IMEI则可能是 MTC UE在附着时提供 给网络的, 也可能是网络根据需要的向 MTC UE查询获得的。
C) MTC UE在 MME上的上下文信息, 例如, MTC UE的当前位置区域 (这些位置区域可以是: TA区域、 Cell小区)、 MTC UE当前的状态 (如:
MTC UE当前是附着状态、 连接状态、 空闲状态等)。
(三 ) MTC Server向移动 '1"生管理网元订阅 MTC UE的相关事件通 口 由于业务管理的需要, MTC Server需要及时获知底层接入层 载层发 送的事件 (如 MTC UE从网络附着、 去附着、 位置变更等), 并根据这些事 件做出相应的决策, 以控制 MTC UE的行为, 因此, MTC Server可以向移 动性管理网元订阅这些接入层 /承载层事件,移动性管理网元则在相应的接入 层 /承载层事件发生时, 及时向 MTC Server上报事件通知, 该事件通知中携 带有 MTC UE的当前信息。 在该种情况下, MTC Server的处理与上述 (二)的处理基本相同, MTC Server在向移动性管理网元发送订阅 MTC UE的相关事件的查询请求前, 也 需要获取为该 MTC UE 分配的移动性管理网元的地址, 具体方法与上述相 同, 在此不再赞述。 与上述(二)的区别在于, MTC Server向移动性管理网元发送的查询请 求是用于订阅 MTC UE的相关事件的, 即请求移动性管理网元在与 MTC UE 相关的接入层 载层事件发生时, 向 MTC Server上 4艮事件通知。 图 13为以 E-UTRAN网络为例, MTC Server向 MME订阅 MTC UE的 相关事件, 以获取该 MTC UE的信息的流程图, 如图 13所示, MTC Server 向 MME订阅 MTC UE的相关事件,以获取该 MTC UE的信息主要包括以下 步骤:

5314, MTC Server向 MME订阅与 MTC UE相关的接入层 载层事件; 需要明确的是, MTC Server可以一次仅订阅一个或一类接入层〃 载层 事件, 也可以一次订阅多个或多类接入层 /承载层事件。
5315 , 与 MTC Server所订阅的对应的接入层 /承载层事件发生;
5316, MME在接入层〃 载层事件发生后, 主动向 MTC Server上 4艮这 些接入层 /承载层事件的情况。 在图 13所示的流程中, MTC Server向 MME所订阅的与 MTC UE有关 的接入层 /承载层事件发生, 可以是如下事件中的一种或若千种:
A) MTC UE的签约数据的变化; 当 HSS变更 MTC UE的签约数据后, HSS需要向 MME重新下发新的签约数据, MME收到新的签约数据后, 可 以通知 MTC Server该签约数据有变化、 或直接将新的签约数据发送给 MTC Server;
B) MTC UE的状态变化; 例如, MTC UE附着到网络、 从网络去附着、 由连接态变更为空闲态、 由空闲态变更为连接态, 等; C) MTC UE的位置区域的变化; 例如, MTC UE发生了位置移动等, 向 MME发送了位置更新消息, 等;
D) MTC UE的网络变化; 例如, MTC UE发生了基站、 网络的切换, 向 MME发送了切换消息, 等。 在具体实施过程中, 上述(二)、 (三)所述的获取 MTC UE的方法可以 单独使用, 也可以结合使用。 具体地, 在上述图 12 所示的流程中, 在步骤 S213中 MTC Server向 MME请求的 MTC UE的信息中可以进一步包括:
D)该 MTC UE所发生的移动性事件, 例如, MTC UE附着到网络、 MTC UE从网络去附着、 MTC UE位置更新、 MTC UE发生基站切换、 MTC UE 发生网络切换等。 则在上述事件发生时, MME将向 MTC Server发送事件通知, 从而使 MTC Server获知该 MTC UE当前发生的事件,以及该 MTC UE的当前信息。
MTC Server也可以在图 12的步骤 S215后, 获取到 MTC UE的当前信 息后, 进一步执行图 13中的步骤 S313及其之后的步骤, 或者, 在上述步骤 S212后, 同时执行步 4聚 S213和步骤 S313 , 以订阅 MTC UE的相关事件, 从 而在这些事件发生时, 通过 MME上艮的事件通知, 获知这些事件的发生, 并进一步获取 MTC UE的当前信息。 如上所述, 在本发明实施例中, MTC Server可以从移动性管理网元获得 MTC UE的信息,具体地可以是 MTC UE的签约数据、 MTC UE的当前状态、 MTC UE 的位置区域信息等。 该获得 MTC UE信息的方式, 可以是 MTC Server主动向移动性管理网元查询,也可以是 MTC Server向移动性管理网元 订阅相关的事件后, 移动性管理网元在事件发生时通知 MTC Server, 或者可 以是移动性管理网元根据 MTC UE的签约数据中的指示, 主动将接入层 /承 载层事件通知给 MTC Server。 在具体应用中, MTC Server可以从底层接入层 载层获得 MTC UE的 信息, 由此, MTC Server可以凭借这些信息, 判断 MTC UE的行为, 并进 一步做出业务层决策,例如,当 MTC UE在非允许时间内接入时, MTC Server 可以要求去附着该 MTC UE; 或者, 当 MTC UE移动到非允许区域时, MTC Server可以要求去附着该 MTC UE等。 虽然在上述实施例中以 E-UTRAN ( EPS ) 网络为例来描述, 事实上, 对 于 GERAN/UTRAN网络的 GPRS接入, GERAN/UTRAN网络中的 SGSN相 当于 E-UTRAN网络中 MME, 充当 PS域的接入控制、 移动性管理功能, 而 GERAN/UTRAN网络中的 GGSN相当于 E-UTRAN网络中的 SGW+PGW, GERAN/UTRAN中的 HLR相当于 E-UTRAN网络中的 HSS。 因此, 才艮据本 发明实施例的上述描述, 本领域技术人员可以直接将本发明实施例提供的上 述技术方案应用到 GERAN/UTRAN网络中的 PS域。 需要说明的是, 在附图的流程图示出的步骤可以在诸如一组计算机可执 行指令的计算机系统中执行, 并且, 虽然在流程图中示出了逻辑顺序, 但是 在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤。 如上所述, 在本发明实施例中, MTC Server通过移动性管理网元可以获 取接收层 载层的 MTC UE的信息, 进而可以才艮据获取的 MTC UE的信息 对 MTC UE进行有效控制, 以实现 MTC Server对 MTC UE的智能管理、 实 时监控等业务。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 或 者将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制 作成单个集成电路模块来实现。 这样, 本发明不限制于任何特定的硬件和软 件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
